Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503222, here are decompositions:

5 + 31503217 = 31503222
13 + 31503209 = 31503222
19 + 31503203 = 31503222
41 + 31503181 = 31503222
43 + 31503179 = 31503222
71 + 31503151 = 31503222
83 + 31503139 = 31503222
103 + 31503119 = 31503222

Showing the first eight; more decompositions exist.
